Hi
I am getting a problem in executing the assembly in app domain

ClassLibrary1 is the assembly and i contains the only one method TestMethod()

In this Testmethod will access the website "www.google.com"

if i call like this its Working fine, but i need to call this through the appdomain.
ClassLibrary1.Class1.TestMethod();

my sample code is:

object[] hEvidence = {new Zone (System.Security.SecurityZone.Internet) };
     Evidence AppEvidence = new Evidence(hEvidence, null);
     AppDomain d = AppDomain.CreateDomain("ClassLibrary1domain");
     d.ExecuteAssemblyByName("ClassLibrary1", AppEvidence);
     AppDomain.Unload(d);

Here i am creating the appdomian with only the privileges access to the Internet
i am getting the Error

Request for the permission of type 'System.Security.Permissions.UIPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

What it is the problem, where i am going wrong.

Solution 1

Did you read the error message? It is quite clear what the problem is, something in your secondary assembly is requesting the UIPermission privilege and it isn't allowed to do it.

WebRequest only requires the WebPermission (according to its documentation), so I guess you are doing something else you haven't told us. For example Console.WriteLine requires UIPermission, as does MessageBox.Show.

namespace ClassLibrary1
{
public class Class1
{
public static void TestMethod()
{
ProcessStartInfo sInfo = new ProcessStartInfo("www.google.com");
Process.Start(sInfo);
}
}
}
this thing i am doing in the ClassLibrary1

You should really read the documentation. Process.Start can't be used from partially trusted code (which makes sense since what you start isn't in the sandbox and could do anything).

I don't know what you're actually trying to do here. Why start a new AppDomain to launch a browser? You can do that from the main AppDomain.
